My repair to my monster trucks manifold was not good enough and it simply became detached again. This time I used permanent threadlock to seal the nuts to the manifold holding it in place. The only way you are supposed to be able to get threadlock off is with a heat gun meaning the engine vibrations will not loosen it.
I took the truck out for a good run along the beach which was a great test of its off road capabilities. Unfortunately I cracked an exhaust coupling on my second tank of fuel!
